[PWGLF] Added background computations for the k892hadronphoton by Oussama3030 · Pull Request #16728 · AliceO2Group/O2Physics

Oussama3030 · 2026-06-18T13:18:34Z

Changes:

Added the file k892hadronphotonBkg.cxx , which is used to calculate the correlated background for the invariant mass spectrum in k892hadronphoton.cxx .
Minor MC related fixes in k892hadronphoton.cxx
Put the axis in sigma0builder.cxx in a configurable group.
